12V 300Ah LiFePO4 Lithium Battery, Rechargeable Two-in-One Mode Battery | Built-in 200A BMS & APP Monitoring, 2560W Max Load, High /Low Temp Protection, for RV, Trolling Motor, Solar, Off Grid, etc.

Features

• Built-in temperature cut-off design over 167F (75C), charge and discharge will be automatically disabled. This battery also resists damage in frigid environments, with an operating temperature span of -4F (-20C) up to 140F (60C).
• Enhanced Safety & 200A Upgraded BMS Fitted with premium Grade A cells and an upgraded 200A BMS. It offers full protection against overcharge, over-discharge, overcurrent, short circuit and extreme temperatures, plus automatic cell balancing. The integrated BMS will cut off power once discharge current goes beyond the safe limit, delivering reliable and secure operation.
• Flexible Capacity Expansion Max capacity reaches 61.44kWh, starting at 3.84kWh. Connect 16 batteries via 4P4S connection for simple system expansion. It outputs 2.56kW to 40.96kW, perfectly suited for RVs, home emergency power and off-grid applications.
• 2-in-1 Smart Dual-Mode Battery Our smart BMS delivers dual functionality for both energy storage and engine starting. It runs as a 300Ah deep-cycle battery with 5,000+ cycles to handle backup power needs. Switch to startup mode, and it produces 1500A instant current with the strong high-discharge capability of LiFePO4 cells. The built-in isolated protection ensures sudden high currents wont wear down the batterys lifespan.
• Smart APP Monitoring Track real-time battery data including voltage, current, power, SOC and cycle count via the dedicated APP. These readings help you regulate charging properly and prevent overcharging, effectively prolonging the battery's service life.
• Rapid Charging & Multi-scenario Use Compatible with solar, generator and 14.6V 70A LiFePO4 charger. An 850W MPPT solar panel fully charges it in roughly 4.5 hours, much faster than lead-acid batteries. Great for RVs, boats, garden tools, off-grid setups and outdoor electronics.
